Alaska Cruise Packing List for May: Exactly What to Pack for Cruise Ships, Shore Excursions, and Glacier Days

If you’re planning an Alaska cruise in May, the most important thing to understand is this:
Alaska packing is not the same as packing for a Caribbean cruise.
Instead of sundresses and flip-flops, Alaska cruises are all about layers, smart gear, and flexibility for unpredictable weather.
The good news? With the right Alaska cruise packing list, you’ll be comfortable whether you’re sitting in the hot tubs watching glaciers, exploring rugged trails on a shore excursion, or enjoying formal nights on board your cruise ship.
May is actually one of the best times of year to cruise Alaska. It falls into the shoulder season of the Alaska cruise season, meaning fewer crowds, beautiful snow-covered mountains, and fantastic wildlife viewing.
